provide a gas burner target having two angular ears, one of which is bent at an angle with relation to the body portion, and the other of which is bent at an angle different from that of the first mentioned angle; to provide a gas burner target having at its opposite sides ears of difierent angularity so that one ear will cause a shorter flame and the other ear will cause a longer flame; and to provide a gas burner target which is formed with a general inclination from one edge to the other.

Other objects and advantages will become readily apparent from the following detailed description taken in connection with the accompanying drawings, wherein:

- Fig. l is a fragmentary vertical section through a gas burner and combustion chamber of a furnace, and including one form of a target embodying our invention.

Fig. 2 is a fragmentary side elevation on a larger scale of a portion of the burner tube and the target of the device of Fig. l.

Fig. 3 is an end elevation of Fig. 2 looking toward the left hand side thereof.

1 :Fig. 4 is a top plan view of Fig. 2.

Fig. 5 is a transverse section on a smaller scale, and taken on the line 55 of Fig. 1.

While our invention further resdes in the combination, construction and arrangement of parts illustrated in the accompanying drawings, we have shown therein for illustrative purposes only, preferred embodiments, and wish it understood that the same are susceptible of modification and change without departing from the spirit and s'co'pe'fof the appended claims.

In the form shown in the drawings, the target is a flat metal plate I5, somewhat elongated and having angularly extended wings or ears l6 and ll at its opposite ends. Plate l5 has secured thereto, by welding or other suitable means, on

tube 22 by clamping ring 23. Ring 23 securely clamps arms 29 and 2! against the sides of the burner tube by tightening the clamping screw 24 which when loosened permits removal of the target plate l5 for repairs, adjustment or substitution of a new plate. A burner tube 22 is shown in operative position in an inlet 8 of a furnace chamber I4.

As seen in Fig. 4, ear iii of plate I5 is inclined at an angle of 60 degrees to the longitudinal axis of the burner tube, and ear I! is inc ined at an angle of 45 degrees thereto. This means that the ear l6 forms an angle of 30 degrees, and the ear I! forms an angle of 45 degrees, with the plate l5, which latter constitutes the body of the target. This structure results in the ear I! causing a shorter flame and the ear l6 causing a longer flame which will be better understood in Fig. 5, in which the shorter flame is indicated by the curved arrows 25and the longer flame is indicated by the curved arrows 26. This causes a more or less centrally located full flame in the its two side edges and midway of its length, the

flanges l8 and IQ of a pair of metal bars o;g arms, .2l| and 2| which at their opposite ends Qi P in Opp te $1665 9? a burner ll fiame the outlet end of a burnehtubfsaid lower portion of the combustion chamber, resulting in a much more complete combustion, and a better control of the two flames with relation to the heating element. The gas burner target of the form here described will preferably be formed of stainless steel, but other suitable material may be used as desired.

We claim:

1. A gas burner target adapted to receive the flame from the outlet end of a burner tube, said target comprising a plate having a flat portion positioned in a vertical plane at right angles to the longitudinal axis of the burner tube and of a greater length in a horizontal direction than its width in a vertical direction, said flat portion having an inclined wing at each end, one of said wings being inclined at an angle of 30 degrees and the other wing being inclined at an angle of 45 degrees outwardlyand toward the burner tube with relation to the plane of the flat portion, each of said wings being flat, whereby the 45 degree wing will produce a shorter flame than the 30 degree wing.

2. A gas burner target adapted to receive the flame from the outlet end of a burner tube, said target comprising a plate having a flat intermediate portion and an inclined ear at each end, the inclination of the ear at one end of the plate being at a difierent angle from that of the ca at the other end. target adapted to recei e? the i as burner target comprising a plate having a fiat intermediate portion and an inclined car at each end, the inclination of each of said ears being at an acute angle outwardly with relation to the plane of the intermediate portion, one of said ears being inclined at an angle of 30 degrees and the other ear being inelined at an angle of 45 degrees.

4. In fii bifid tiofr gas bfitfrftfifg't; a gas burner tub'haii/ir'ig an open'fiafn-propelling nd, said target comprising a plate having a fiat interi0 mediate portion extending at right angles to the longitudinal axis of the burner tube and positioned a distance from the nozzle, said plate Having an inclined ear at each 'fid} 4 nected to the plate on its vertically opposite edges.
